How to Conduct an Ad Hoc Blood Sugar Experiment Using Fulcra, Dexcom Stelo, and a Food Tracking App

By combining continuous glucose monitoring (CGM) with dietary tracking apps and platforms like Lose It!, users of Fulcra’s iOS Context app can run a personalized blood sugar experiment to fine-tune our lifestyle choices.

In an age where personal health data is becoming more accessible, many of us are interested in understanding how our bodies react to daily habits—especially diet. By combining continuous glucose monitoring (CGM) with dietary tracking apps and platforms like Lose It!, users of Fulcra’s iOS Context app can run a personalized blood sugar experiment to fine-tune our lifestyle choices. This blog post will guide you through how to set up and conduct an ad hoc blood sugar experiment using the Dexcom Stelo CGM, Fulcra/Context, and a food tracking app like Lose It!.

Why Monitor Blood Sugar?

Your blood sugar levels fluctuate based on a variety of factors including the types of food you eat, stress, exercise, and sleep. By continuously tracking glucose levels, you can pinpoint how your body reacts to different types of foods, meal timings, or activities. This insight can lead to better health management and a more optimized lifestyle.

What You'll Need

1. Dexcom Stelo CGM: A continuous glucose monitoring device that will provide real-time glucose readings.

2. Lose It! App: A popular food tracking app that lets you log meals, snacks, and beverages for detailed nutritional information.

3. Fulcra Platform: A private data platform that allows you to collect and analyze your personal health data from multiple devices in one place.

Step-by-Step Guide to Conducting Your Experiment

Step 1: Set Up the Dexcom Stelo CGM

The Dexcom Stelo is a lightweight and easy-to-use CGM device that offers continuous glucose tracking, making it perfect for running your own personalized health experiment. Follow these steps to set up the device:

  1. Purchase the Dexcom Stelo from their official website Stelo.
  2. Install the companion app to get real-time glucose readings on your smartphone, and connect to Apple Health.
  3. Set up notifications to alert you if your blood sugar rises too high or dips too low.

  

Once installed, the CGM will start providing continuous glucose data, ready to be analyzed later in the experiment.

Step 2: Set Up the Lose It! App for Meal Tracking

The Lose It! app makes it easy to track everything you eat and drink. By combining your food log with glucose data, you’ll be able to identify specific meals or foods that might be spiking your blood sugar.

  1. Download Lose It! from the official website or your app store.
  2. Connect Lose It! to Apple Health
  3. Start tracking all your meals and snacks. Be as detailed as possible, including portion sizes, meal times, and even beverages.

  

The more precise your food log, the more accurate your insights will be when you analyze the data later.

Step 3: Download Context to collect your CGM, Food and other Health and Fitness Data

Fulcra is a powerful data platform that allows you to collect and secure personal data streams, such as those from your Dexcom Stelo CGM, empowering you to conduct personal data science to optimize your life. Here’s how to integrate your CGM with Fulcra:

  1. Download and install the Fulcra Context app from the App Store.
  2. Log in with Google or Apple and grant Context access to your data
  3. Visit Fulcra’s Portal to see all of your data in one place
  4. Explore Fulcra’s GitHub demos to see how you can take your personal data science further with computational notebooks. 

 

Step 4: Design Your Experiment

Once everything is set up, it’s time to design your experiment. Here are a few considerations to make sure you collect meaningful data:

  1. Define a goal: What do you want to learn? Are you curious about how certain foods (like carbs or sugar) affect your glucose levels? Or maybe you want to understand how your glucose changes after fasting or during specific exercise routines?
  2. Set a timeframe: Decide how long to run your experiment. A week or two might be ideal to capture a variety of meals and activities.
  3. Create meal hypotheses: Predict how different foods will impact your blood sugar. This will make it easier to interpret the results later.
  4. Track sleep and activity: Sleep and exercise can also affect glucose levels, so consider tracking these as well for a more comprehensive view of your health.

Step 5: Run the Experiment

Now that everything is in place, it’s time to conduct your experiment. During this phase, track all meals and snacks in the Lose It! app, making sure to log time and portions.

Step 6: Analyze the Results with Fulcra

After your experiment period, it’s time to dive into the data. Fulcra makes it easy to visualize your glucose trends and correlate them with your food intake.

  1. Visit Portal to see how various foods and meal timings impact your blood sugar readings. 
  2. By configuring Timeline so your blood sugar and net calories data are adjacent, it’s easy to visualize how your eating habits are affecting your blood sugar and overall health. 

Step 7: Draw Conclusions and Adjust Habits

Once you have analyzed the data, it’s time to make data-driven decisions:

  • Identify food triggers: Determine which foods or meals lead to blood sugar spikes or crashes. Are there particular meals that tend to cause issues? This can help you adjust your diet to better stabilize your glucose levels.
  • Refine meal timing: You might notice that eating certain types of food at different times of the day impacts your glucose in unique ways.
  • Optimize lifestyle: By understanding how sleep and exercise influence your blood sugar, you can make more informed decisions about how to balance all aspects of your health.

Step 8: Iterate and Optimize

Conducting this experiment is just the beginning. Once you have a better understanding of how your body responds to food and other lifestyle factors, you can continue to refine your habits. Use the data from Fulcra to optimize your diet, meal timing, and even your exercise routines. Repeat the experiment periodically to stay on top of how changes in your life may impact your glucose levels.

Conclusion

By combining the power of a CGM like Dexcom Stelo, Fulcra for data aggregation, and a food tracking app like Lose It!, you can run a highly personalized blood sugar experiment. This setup offers you an unprecedented level of insight into how your body responds to daily habits, empowering you to make smarter choices that lead to better health outcomes. The result is a deeper understanding of your glucose patterns and a more optimized approach to nutrition and lifestyle.
